Ocular pulse amplitude in patients with open angle glaucoma, normal tension glaucoma, and ocular hypertension
Background/aim: Intraocular pressure (IOP) is not a fixed constant value but rather has pulsatile components associated with cardiac action. The SmartLens dynamic observing tonometer (odc, Ophthalmic Development Company AG, Zurich, Switzerland) can measure and record simultaneously IOP and ocular pulse amplitude (OPA). It was the aim of this study to evaluate OPA in patients with primary open a...
متن کامل[Ocular pulse amplitude in patients with open-angle glaucoma, normal-tension glaucoma, and ocular hypertensionby dynamic observing tonometry].
PURPOSE The aim of this study was to compare the ocular pulse amplitude (OPA) in patients with different types of glaucoma, and also to evaluate the usefulness of OPA for the elucidation of normal-tension glaucoma (NTG). OPA is thought to reflect choroidal circulation. SUBJECTS Sixty-six patients with normal-tension glaucoma (NTG), 52 patients with primary open angle glaucoma (POAG), 42 with ...

متن کاملCorrelation between ocular perfusion pressure and ocular pulse amplitude in glaucoma, ocular hypertension, and normal eyes
BACKGROUND The purpose of this study was to investigate the correlation between ocular perfusion pressure and ocular pulse amplitude in glaucoma, ocular hypertension, and normal eyes. METHODS Ninety eyes from 90 patients were included. Thirty patients had been recently diagnosed with glaucoma and had no previous history of treatment for ocular hypotension, 30 had elevated intraocular pressure...
متن کاملFactors affecting ocular pulse amplitude in eyes with open angle glaucoma and glaucoma-suspect eyes.
PURPOSE To investigate the associations between ocular pulse amplitude (OPA) as measured by dynamic contour tonometry (DCT) and ocular and systemic factors in patients with open angle glaucoma (OAG) and in glaucoma suspects. METHODS One hundred and seventy-three glaucoma-suspect patients were consecutively enrolled. All subjects underwent intraocular pressure (IOP) measurement by DCT and Gold...
